WHEEL-FLANGE OILER.

Specification of Letters Patent.

Application filed June 1, 1911. Serial No. 630,640.

and WALTER A. 'BAIsLnY, both citizens of the United States, residing inthe city and county of San Francisco andState of California, haveinvented new and useful Improvements in Wheel-Flange 'Oilers, of whichthe followingis a specification.

This invention relates tolubricators for the flanges of car wheels, andthe like.

The object of the invention is to provide a simple and practical devicefor applying oil, or other lubricant, directly and economically into thefillet of locomotlve wheels, etc., for the purpose of preventing wear onthe flanges and rails.

The invention consistsof the parts and the combination and constructionof parts,"

as hereinafter more fully described and claimed, having reference to theaccompanying drawings, in which Figure 1 1s a slde elevation of a partof a locomotive showing the application of the invention. Fig. 2 is aplan viewof the same. Fig. 3 is a longitudinal section through the mainpart of the lubricator. Fig. 4 is an end view in partial section of thesame.

A is a valve casing, suitably secured in juxtaposition to the wheel tobe lubricated, and represented at 2. As here shown, this valve casing isrigidly supported by a bracket 3, Fig. 2, on a suitable part of theengine frame. As shown in Fig. 3, the casing is cored out to accommodatea plug 4, which has an outwardly seating valve head 5 adapted to fitagainst a corresponding seat formed in the nipple 6, which screws intothe casing. The valve 5 is normally pressed against its seat by means ofa spring 7 surrounding the plug or stem 4.

The portion of the nipple 6 beyond the valve has an enlarged chamber toaccommodate a piston or a plunger valve 8, which has a snug sliding fitwithin its cylindrical enlargement. The plunger or piston 8 has a guidestem 9 fitting a cavity in the adjacent reduced extension of the plug 4,and centers the plunger 8 with respect to the plug and valve 5. Theplunger 8 has a valve portion 10, movable toward and from acorresponding seat 11 in nipple 6; an air vent 12 allowing a free actionof the piston and plug.

A union 13 screws into the top of the nipor other fluid pressure supplypipe 14, Figs.

7 land 2, for receiving steam from the steam .chest, or otherappropriate source of fluid supply. Whenever the steam pressure is onthe top of the piston or plunger 8, the latter is moved down to closethe seat 11, at the same time pushing :down on plug 4, compressingspring 7 and movingvalve 5 away from its seat to admit oil from ,pipe'15 into communication :chamber 16 within the casing A, and in whichchamber 16 the reduced portion of rthe plug 4 is adaptedto work; pipe 15being shownas-tapped into one side of the casing A, and there beingsuitable ports 17 which penetrate the valve chamber, and which ports arenormally closed by the valve 5. @Pipe 15 leads to any suitable source ofoil supply as the tank 18, from which the oil may flow to the casing,and thence to the wheel flange when permitted, by gravity. 19 land20 aresuitable cocks in the oil supply pipe. In fact, thesame oil that is usedfor fuel may be used for lubricating.

The chief feature of the present invention resides in the means by whichthe oil admitted into the chamber 16 is delivered on to the wheelflange. One essential of the lubricant applying means is that it must beapplied directly to .the flange rather than sprayed or projected thereonby a jet. Some sort of frictional means is desired, if not essential;and such means must be capable of instant and automatic adaptation toany irregularities in wear on the flange, must bear wit-h even pressure,must not be subjected to too great wear, and must be capable of readyre-placement when worn to any considerable degree, so as not to impairits effectiveness. To this end I use a brush made up of a series ofwires, or fine, flexible rods 21 carried in a counter-weighted holder22, swiveling on a reduced hub extension 28 of a coupler 24, which isscrewed on, or is otherwise attached to the casing A. This coupler 24has a central passage 25 in continuation of the chamber 16 and from thispassage 25 extends outwardly one or more radial ports 26, discharginginto an annular groove 27 in holder 22, from which groove 27 thelubricant may flow through a port 28, into the socket within which thebrushes 21 are held by suitable means, as the clamp screw 29.

30 is a counter-weighted arm, suflicient to cause the brushes 21, whichhave their ends cut on a bevel, as shown at 31, to bear the oil supplywith the valve with just the right pressure continually in the fillet ofthe wheel, and against the inner side of the wheel flange. Thecounterweighted holder 22 is suitably held in place on its hub 23, so asto be freely turnable thereon by any appropriate means, as the nut 32.

In practice the lubricator is suitably mounted upon the engine or othervehicle, substantially in the manner as shown in Figs. 1 and 2, so thatthe brush 21 will bear against the wheel flange and the device connectedup to suitable sources of steam and oil supplies. In running down-gradeor operating on curves, the operator simply turns a three-way valve 33to admit steam through the pipe 14 to the'outer end of the plunger orpiston 8. This results in an inward movement of the plunger and of theplug 4 until the plunger seats snug on the seat 11, thereby sealing thesteam off from the oil supply. The inward movement of the plunger 8 toits seat 11 opens valve 5 and allows the oil to pass from pipe 15through port 17, and around the valve 5 into chamber 16, thence throughpassage 25 and ports 26-27 and 28 into the socketed head of the brush21; the oil thence flowing down through the numerous channels and ductsformed by and between the wires of the brush. The holder 22, beingswivelly n;ounted and counter-weighted, bearsCOnstantly with just enoughpressure to insure the application of the oil or other lubricatingfluid, in proper manner, to the inside of the flange. By this swiveledbrush the right quantity of lubricant is delivered in just the rightplace. Cutting off the steam supply through pipe 14, and exhausting thehaving ports registrable with said oil outlet, a lubricant distributingmember carried by the holder, and fluid pressure means controlling theintermittent flow of oil between said inlet and'outlet.

2. In a lubricator, the combination with the part to. be lubricated, ofa casing, and a counter-weightedmember swivelly mounted on the casing, abrush carried by the counterweighted member in yielding frictionalcontact with the part to be lubricated, and means for feeding thelubricant to the brush through said casing.

8. In a lubricator the combination of a the swivelly mounted member, anda distributer carried by the swivelly mounted member and adapted tocontact with the part to be lubricated.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
